AI Technical Summary
Existing beam-controlled antennas/arrays suffer from problems such as large size, high cost, complex structure, and difficulty in achieving flexible multi-beam switching, making them particularly unsuitable for miniaturized and low-cost wireless communication applications.
A miniaturized reconfigurable antenna was designed, employing a substrate-integrated waveguide unit and a phase-reconfigurable metasurface structure. The radiation phase and amplitude are controlled by electronic switches, achieving 1-bit and 2-bit digital phase and amplitude modulation, which simplifies the control structure and reduces costs.
It achieves flexible beam control and beamforming capabilities, making it suitable for miniaturized communication devices and meeting the wireless communication needs in low-cost and space-constrained scenarios. It also has the advantages of high bit depth and multiple digital modulation dimensions.
